Sulfide Chemical

Ammonium Sulfide

CAS No      12135-76-1

Application / Uses Preparation
Ammonium sulfide, is an unstable salt with the formula (NH4)2S. Aqueous solutions purporting to contain this salt are commercially available. With a pKa exceeding 15,[2] the hydrosulfide ion cannot be deprotonated to an appreciable amount by ammonia. Thus, such solutions mainly consist of a mixture of ammonia and (NH4)SH.

Potassium Sulfide

CAS No      1312-73-8

Application / Uses Preparation
Potassium sulfide is the inorganic compound with the formula K2S. The colourless solid is rarely encountered, because it reacts readily and irreversibly with water, a reaction that affords potassium bisulfide (KSH) and potassium hydroxide (KOH).

Sodium Sulfide

CAS No      1313-82-2

Application / Uses Preparation
Sodium sulfide is the name used to refer to the chemical compound Na2S, but more commonly it refers to the hydrate Na2S·9H2O. Both are colorless water-soluble salts that give strongly alkaline solutions. When exposed to moist air, Na2S and its hydrates emit hydrogen sulfide, which smells much like rotten eggs or flatus.

Zinc Sulfide

CAS No      1314-98-3

Application / Uses Preparation
Zinc sulfide is a chemical compound with the formula ZnS. Zinc sulfide is a white to yellow-colored powder or crystal. It is typically encountered in the more stable cubic form, known also as zinc blende or sphalerite.[1] The hexagonal form is also known both as a synthetic material and as the mineral wurtzite.[
